Manchester encoding is used on 10 Mbps Ethernet, Differential Manchester encoding is used on token ring.

Thanx for that any idea about the symbols?

Re: Manchester symbols [7:6655]
The original 10-Mbps Ethernet II and 802.3 standards use Manchester encoding for all media types. Manchester encoding specifies that a bit period is divided into two equal intervals and there is always a transition from either high to low or low to high in the middle of the bit period. A binary zero is high first and then low. A binary one is low first and then high. I haven't heard these called symbols, but perhaps your reference calls them symbols.

Re: Manchester symbols [7:6655]
i remember the term symbol as equated to a state change. in modulation techniques where 1 symbol = 1 bit, the symbol rate and the bit rate are the same. some modulation techniques can yield multiple bits from a single symbol. qpsk (quaternary phase shift keying) is a form of phase angle modulation used in rf where 1 symbol = 2 data bits. so the symbol rate is 1/2 the bit rate (23 megasymbols per second = 46mbps).
